Piston Ring Set 4.470 Bore .017 1/16 3/16

The Piston Ring Set 4.470 Bore .017 1/16 3/16 by Total Seal is designed for serious engine builders and high-performance mechanics who require precision compression control and reliability under extreme conditions. This ring set is essential for custom builds, racing applications, and performance restorations where factory specifications may not suffice.

Engineered for engines requiring exact bore diameter matching, this piston ring set features a three-piece design that includes a compression ring, wiper ring, and oil control ring. This design minimizes blow-by, reduces friction, and maximizes combustion chamber sealing across the entire RPM band. The .017 top ring gap specification, along with the 1/16 inch second ring width and 3/16 inch oil ring width, ensures precise clearance for the 4.470 bore diameter.

This piston ring set is ideal for those assembling stroker motors, rebuilding vintage V8s, or fine-tuning competition engines. Its balanced geometry prevents ring flutter at high RPMs while delivering superior oil control and reduced carbon buildup, making it critical for engines that experience sustained boost, nitrous oxide, or continuous wide-open-throttle operation.
